慈悲與智慧也。此為佛菩薩所具一雙之德，稱曰悲智二門。智者，上求菩提，屬於自利，悲者，下化眾生，屬於利他。以之配於人身之兩手，則悲為左手，智為右手。又配於真言之兩部，則悲為胎藏界，智為金剛界。配於彌陀之兩脅士，則悲為左脅之觀音，智為右脅之勢至。有如是無盡之對配。法事讚上曰：「釋迦諸佛，皆乘弘誓。悲智雙具，不捨含情。」
Pity and wisdom; the two characteristics of a bodhisattva seeking to attain perfect enlightenment and the salvation of all beings. In the esoteric sects pity is represented by the Garbadhātu or the womb treasury, while wisdom is represented by the Vajradhātu, the diamond treasury. Pity is typified by Guanyin, wisdom by Mahāsthāmaprāpta, the two associates of Amitābha.
一悲智 指救度眾生之慈悲與求菩提之智慧。佛菩薩具此二種功德，合稱為悲智二門。善導法事讚卷上即謂，釋迦及諸佛等，皆乘其弘誓，悲智雙行，不捨有情眾生。此二者中，智慧屬於自利，慈悲屬於利他。若配於人之兩手，則悲為左手，智為右手；若配於密宗之金胎兩部，則悲為胎藏界，智為金剛界；若配於阿彌陀佛之兩脅士，則左脅之觀音菩薩表悲，右脅之大勢至菩薩表智。完全實現此悲智二門，稱為悲智圓滿，唯佛能達此一境界。p6237
慈悲與智慧，是佛菩薩所必備的二種德性，也叫做悲智二門。智是上求菩提，屬於自利；悲是下化眾生，屬於利他。
